    I have purchased the Amp Combo above in the subject line.  I would like to know if this amp will accomodate a 10 or 12 inch speaker to replace the 8 inch that it is going to arrive with.

    This is all new territory for me, but I have a 10" 35 watt to use in this 15 watt combo.

    Thanks for your help

      Pardon my translating software


      Hola, creo que puedes usar tu amplificador en casi cualquiera de esos lugares, tal vez no en una arena . En cuanto a los oradores, creo que eso también se basa en la necesidad. Creo que con los altavoces de 8 ohmios tienes alrededor de 400 vatios por lado, la potencia aumenta en función de lacarga hasta el máximo. Se duplica aproximadamente a medida que aumenta la carga. 800 vatios para 4 ohmios, 1500 para 2 y 3000 valores reales de adivinación en puente, pero esto debería estar cerca.

      Behringer NX3000 Specs



      • 2 Ohms: 1500 W per Channel.

      • 4 Ohms: 900 W per Channel. 3000 W Bridged.

      • 8 Ohms: 440 W per Channel. 1500 W Bridged.

    Recently, my audio set up has stopped working. The Nu3000’s display lights are red and now the audio only plays in a short burst when I first turn the amp on. During this burst, the indicator light for the channel I’m using will flash from red to orange before returning to red.

    The board where I’m inputing the audio feed is picking up the audio (the L/R audio light bars are jumping to the beat of the songs, so I know that’s working). Additionally the speakers, as indicated by them being able to play those short burst so of music seem to be working fine. 

    Does anybody have any help they can provide? I have an event coming up in a week that I need to be ready for.

    Thanks for your help in advance. More details of my setup follow.

    This audio set up has been working for years with an inuke nu3000 amp, an Allen & Heath zed10fx board, and two electro voice  ekc-15 speakers.

      Does the amp do the exact same thing (red, then orange for a second, then red again),  when no speakers or inputs are connected?

    When I plug in my new PPA500 - lights on the display blink randomly. There is no proper connection and the system is unusable. I have tried a new fuse. 
    Any suggestions are welcome. Thanks guys.

      Hello Bo, welcome to the community.


       


      If it is new (<30 days), I would contact your supplier for a return/replacement. Otherwise I suggest that you raise a Care ticket for Service Repair explaining your problem. This is done by clicking on Support at the top of the page and then clicking the Create a Care Ticket button. This is only possible if you have completed all the required fields in your profile. Make sure that you fill-in every required field on the Care form.


       


      Keep a watch on your email spam folder. Some replies from the Care team have been missed that way.

    Greetings,

    I am a disabled vet on a very limited income. I own 2 Behringer NU6000DSP's that both have went bad in the last 3 years, last one occuring just days ago. The first time was under warranty and NEVER heard anything back from anyone ( believe me am persistant) I thought it would have been quicker acting with manufacturer then submitting to Sweetwater service (1st kick in the pants) Even have a repair vacility 30 miles away.... did everything except throw rocks through windows to get help! Still nothing.

    Now all this tribe stuff... I don't need a forum, I need service PLEASE! Ticket submission said response in under 24 hours (2nd kick in pants) I DJ the local VFW's/Legions for very little money and consider moving the gear my weekly cardio. So without an amp, I won't be doing any gigs which may cause my blood to thicken and I could possibly die!  I know it is a stretch, but seriously, it could happen!

    I don't want to die please help me!

    My setup...minus working amps.My setup...minus working amps.

      Hello Bryan, welcome to the community. We are mostly users like you but we may be able to help.


       


      Did you get any email response from your most recent Care ticket submission? Some people have missed them because they ended-up in their spam folders. You should also be able to see the status of the case by clicking on Support at the top of this page. If you can tell us the Care Ticket Number, we should be able to get someone to look into it.

    Have 3 missing control knobs and corresponding D-shafts - can easily get the control knobs but can't seem to locate the relevant D-shafts, which seem to be differntly size to fit the knob and the receptor

    what a lot of BS to get in here, trying to get to someone to ask whether I can buy an amplifer for my powered speaker (amplifier only already got power supply heat sink speaker and controls) don't want to buy a complete powered speaker box, any ideas

    Hi,

     

    I am new here. I would like to ask some technical question about new Lab Gruppen PDX3000 amp. It seems to be a perfect solution for my JBL4645Cs. First of all I would like to know what is the DAMPING FACTOR (aprox. up to 300Hz)?. For the input on XLRs I would like to connect it directly from the integrated amplifier from speaker terminal (high level to low level); I made some measurements and normally high level does not exceed 0,5V - how much volts can take XLR input on PDX3000?

     

    Thank you very much in advance.

     

    Kind regards,

     

    Gasper Jancigaj

      Hi Gasper,


       


      The following is a white paper published by Lab.gruppen detailing why we do not use Damping Factor in our specifications.


       


      Damping factor


      The damping factor is determined by the quotient of the speaker impedance and the output impedanceof the amplifier. To state the damping factor figure of an amplifier is meaningless, as the speakerimpedance’s varies with the frequency and the various types and brands of loudspeakers existing.The figures of the true damping factor are only valid for a specific amplifier/ loudspeakercombination. This fact gives one of the reasons why Lab.gruppen don’t publishes the damping factorfigures.The only figures that are relevant for amplifiers are the output Impedance figures. Most amplifiers onthe market only show low output impedance (or high damping factor) at low frequencies and high(er)at high frequencies. This is due to the improper design of the output network and/or frequencydependent feedback. Lab.gruppen design has the feature to have nearly constant impedance over theaudio frequency band with a value of 0.05 to 0.07 ohms (50-70 mohms) . This causes less coloration.Another feature of the power supply in the fP 2200 - fP 6400 (thanks to the stabilised power supply),is that the output impedance doesn't rise during clip situations. In most conventional amplifiers theimpedance rise 10 or l00 times during clip. That causes uncontrolled movements of the speaker-cone.The conclusion must be that the Lab.gruppen switch mode power supplies sound better or have betterdefinition, especially in the bass region, compared to conventional designs.


       


      Damping factor influences on active and passive frequency divided loudspeakers


      Another reason not to publish the damping factor is that it’s not relevant to the audio quality of the power amplifier. For example; a professional loudspeaker driver has a DC-resistance between 2 and 5ohms, which is connected in series with the driver in the equivalent circuit diagram of the driver. Inthis case, the damping factor has more to do with the speaker itself than the amplifier, as the speakerdriver is connected directly to the power amplifier just as in an actively divided system (see example below).In a passively divided speaker system the filter network circuit are placed between the power amplifierand the speaker driver. In this case, however, the filter impedance determines the damping factor ofthe speaker driver. The output impedance of the power amplifier can influence the characteristics ofthe filter response, but it’s not sure that a lower impedance (higher damping factor of the poweramplifier) will give a better response. A classical example is the tube amplifier, which has relativelyhigh output impedance and which gives a very good sonic result in most cases.


       


       


       


       


      I am not entirely sure I understand your question,  "For the input on XLRs I would like to connect it directly from the integrated amplifier from speaker terminal". Could you explain what you wish to do in a bit more detail please?


       


      The PDX inputs are Line Level, if you are using an appropriate audio source then it will be a line level output also. What are you planning on using to drive the input on the amplifier?
